By reason of the fact that the disc 12 is- 1925 out of actual contact with any portion of the a aratus exce t throu h the sprmgs' 7, it is o ious that vibrations can reach the tube only through these springs, in which case they are absorbed or dam out. The a rture 14 is made of such s ze that, at no time while in use, does the disc 12 come into contact with the column 9, the weight of the tube being suflicient to keep the springs 7 slightly compressed and the disc 12 out of contact with the abutment 10. The tube, therefore when inserted in the upper disc 12, has a limited vertical movement, as well as alimited horizontal movemeat, and it is at all times supported resil- 1en y.

My improved socket, therefore difiers in many essential respects from resilient sockets heretofore provided. It may be used either for mounting directly on a panel or subanel, or it may be used as an auxiliari hol er in connection with conventional soc ets. It is comparatively cheap to manufacture, is easily' assembled, and is rugged and durable;

A further advantage of my invention li in the fact that the tube is, at all time, refiliently supported, get is not permitted to depart appreciably om its fixed position in a set, either vertically or horizontally, which indicated in the appended claims.
